Congratulations on getting a Graphic. I gather your Crown is a 4x5.
Is the rangefinder on the side of the body or on top?
Do you know how to set the camera up? If not, instructions are here:

If yours has a side RF, there should be a viewfinder on top. The RF and VF are uncoupled, don't communicate with each other. Neither needs a battery. However, the RF (top always, side as an accessory) has a battery powered focusing aid that's used in poor lighting.
If you're using an RH 10, you're shooting 2.25" x 2.75" (6x7 in metric). The normal lens for 6x7 is 90 mm. A 127 mm lens would be quite a long normal lens, 152 mm longer still.
There's no trick to using lenses on Graphics. If the lens is long enough to focus to infinity (on a 4x5 Crown, flange-focal distance >= 52.4 mm) and short enough to focus to infinity (flange-focal distance <= ~300 mm), just put it on a board, mount on the camera and slide the standard to the lens' infinity position.
FWIW, I don't use my Graphics' rangefinders, always focus on the ground glass. Focusing at the lens' hyperfocal distance isn't, in general, practical.
